This patch set adds a clk driver for the low power clocks found in
the CREG block on lpc18xx. CREG is a collection of miscellaneous
configuration registers that can be accessed through a syscon
regmap interface. The clk driver makes it possible to setup and
enabled these two clocks.

This need to support peripherals like the internal RTC on the
lpc18xx platform.

Mike/Stephen is this what you envisioned?
It seems to work, but I currently don't have a setup that requires
the 32khz clock early so that part isn't really tested.

The probe deferral seems to work for the RTC:
[    3.386861] lpc24xx-rtc 40046000.rtc: error getting rtc clock
[    6.737615] lpc24xx-rtc 40046000.rtc: rtc core: registered lpc24xx-rtc as rtc0


Changes since v1:
 - Split driver with one early init and one platform driver
   probe.

Based on v4.5-rc1.
